Here is my small review of the R4i Save Dongle!
Installation
The Installation was bloody easy, just put the dongle into a usb port, that's it! My windows 7 64-bit installed it automatically.
Usage
I just needed to download the R4i SaveDongle V1.1 Software, after starting it the dongle was detected instantly:
The save backup also works just fine, tested it with Ocarina of Time 3D, a 3DS game:
I also restored a different save from another user on games-engine.com, worked fine too. All in all I can say it works perfectly fine for the games I tested and it's really easy to use, it's just working fine with 3DS games, in my opinion currently the best way to modify 3DS and NDS saves, everyone who wants to modify, backup or share a save, this device is just working great, I can recommend it
